Materials Data on LiCuN by Materials Project
LiCuN crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Li1+ is bonded in a linear geometry to two equivalent N3- atoms. Both Li–N bond lengths are 1.97 Å. Cu2+ is bonded in a square co-planar geometry to four equivalent N3- atoms. All Cu–N bond lengths are 2.03 Å. N3- is bonded to two equivalent Li1+ and four equivalent Cu2+ atoms to form a mixture of edge and corner-sharing NLi2Cu4 octahedra. The corner-sharing octahedral tilt angles are 0°.
